Open the front of the printer by pulling on both tabs at the finger grips on both sides of the front panel. The front panel will flip down. The drum and toner cartridge comes out as a single unit. It is black plastic within gray plastic and has a handle like grip in the middle. Grasp this grip and pull the unit up and out. It feels kinda funny the first time you do it and you may feel like it will break, but it won't. Pull it up and out in a kinda circular arc. Do not touch the drum. If you ever need to replace the toner cartridge, press on the blue tap and separate the drum from the toner cartridge. You will have to replace the drum after every five toner cartridge replacements so practice doing it now. Note the tabs and slots on the sides before separating the drum and cartridge. Align the cartridge into the drum carriage and slide it in until it clicks. To replace the cartridge assembly into the printer, angle the cartridge at about 45 degrees and rotate in while pushing. It should click into place. If the front door then closes properly, you should have it in properly. Practice a few times and you should be an expert. For paper jams, there are many places to check and they may not all give warnings. First pull out the paper tray and check for and remove misfeeds. Remove the drum cartridge assembly and described here and check for and remove any paper. Open the back cover and check for and remove any paper. Open the automatic feed and check there as well as lifting the cover where the scanning surface is. Look in the rollers for the automatic feed for paper pieces. The last place almost never gives you a warning. Reach into the slot where the paper exits after being printed and grasp the whole top cover. Lift upward and it will open about 4 inches. This is a good place where small pieces of paper or even whole sheets may get stuck. Clean out any dust while you are there.

After changing the drum, toner and running around town for days trying to find a reliable place to get this printer repaired, I realized I was spending a lot more money than what the printer actually costs. the drum was over $100, toner was $80, and the printer is $250. I bought a new one, and I can now use the old one for parts.

SOURCE: paper jam, and I don't
I had the same problem. I had removed all the visible paper and when it came back on made some awful noises and flashed "paper jam".
I even moved the roller forward and backward (after having uplugged the device. I did this repeatedly and the "paper jam" alert continued (along with the awful noise).
As a last resort I thought I would just take it apart and hope to get it back together but figured it was a sensor or something along that line if I could not find any paper anywhere
with the machine unplugged (it would not shut down), I opened the lid I used a flashligt to look around trying to figure out how to take it apart.
It then dawned on me that I had not moved the print head over and using a screwdriver I gently pushed it to the center of the bar. When I looked inside with a flashlight, there was the paper jam way inside under the cover.
I used some needlenose to reach in and took the paper out and it is now working fine.
I hope this helps, but you may have to search really deep into the device.
